Patrick Durusau commented on OFFICE-1634:
-----------------------------------------

Good point about "data-aware" being a two-way proposition. 

Let me re-say the proposal:

Chapter 12 forms preamble:

Forms can be data-aware. A form is data-aware if the values subject to its controls are obtained from and updated to a database. 

The result set of values subject to the controls of the form is defined by the  form:datasource, form:command, and form:command-type attributes. At any point in time, only one row of the result set is subject to the forms controls.

****
Question: What is meant by "a homogeneous set of rows of data taken from the database? Do you mean it is the result of one query such that all the returned rows have the same column structure? Isn't that in the nature of database queries? 
****

form:data-field:

 The form:data-field specifies the name of a column in the result set defined by a (data-aware) form. A control interchanges content with its column as follows:

   * When the current row of a form changes, the control is initialized with the value from its column.

   * When the user changes the content of a control, this changed value is written back to its column.

Note: Applications may delay this write-back, for instance until the control loses the focus, instead of updating the column value with every change in the control.
